Tom Hanks: "I Hope They Ask Me"

With The Lost Symbol barely on bookshelves, Tom Hanks has let it be known that he is keen to once again play Robert Langdon in the next movie instalment:

just finished it last week. Page-turner. Dan Brown knows how to weave a tale. I was exhausted by the end of it... I'd love to if they're going to do it - I'm not going to walk away from that.... If they make it again, I hope they ask me. If they didn't, what did I do wrong?

Who would be the choices for the supporting actors? Morgan Freeman as Warren Bellamy perhaps, and Linda Hunt as Sato? What about Katherine and Peter Solomon, and Mal'akh?

Hugh Jackman Receives My Vote

Sorry to say I was never happy with Tom Hanks playing the role of Langdon. His comedic background always makes me feel like he is going to crack a joke any minute.

I'm sure Tom will play the role again, but I feel Hugh Jackman would have made a much more believable Langdon. When I watch a movie, I want to forget I'm watching actors.

Did you ever see Jim Carrey in Michel Gondry's 2004 "Eternal Sunshine of the Spotless Mind"? I never thought he could be anything but a comedian (who I had no time for) - but his performance blew me away, no doubt helped by the storyline and director - still, mind-changing stuff (no pun intended).

Tom Hanks HAS to come back!

I really think Hanks should come back. I can't think of anyone else to play the role, really. Hanks is just what I remember Langdon as now, since Dan didn't really make a clear image. But for Peter Solomon, I don't know how good this guy can do an accent, but I vote for Bill Nigh.

Didn't know who he was by name, but I know the face - and my image of Peter Solomon is remarkably close! I like your choice. :)

The Lost Symbol

As I read this book, Linda Hunt came instantly to mind for Sato as did Morgan Freeman as Bellamy. No other actor can play Robert Langdon but Tom Hanks.

Richard Gere would make a terrific Peter Soloman. Sigorny Weaver is Katherine.

Mal'akh is described as a huger person but someone with the talent of Edward Norton is needed to make the transitions with belief.

Who can play Peter

I thought that Patrick Stewart would play a good Peter Solomon. He is a good actor and he is great at showing pain and empathy (Spoiler: For most of the movie the character is in pain). Also, he's old and bald. You can't go wrong here.

The Lost Symbol Characters

Morgan Freeman for Bellamy, Diane Lane for Katherine, Josh Hartnell for Mal'akh, Ed Harris for Peter Solomon, Kirsten Vangsness for Katherine's assistant, Linda Hunt fof Sato. Even though there could have been a better choice for Robert Langdon in the beginning, now that Tom Hanks in in two films you cannot change him.

I think Dennis Haysbert would be a much better Warren Bellamy. You may know him from the unit or the alstate ads. Edward Nortin as mal akh? I think you could find someone much better

I also tought of Morgan Freeman as Bellamy, but I am also thinking of Samuel L. Jackson.
As Katherine and Peter I have problems finding the right one I think is perfect for the role.
For Mal'akh I was thinking of Ralph Fiennes. (when reading I was seeing him in front of me, as he was playing in "Red Dragon".
As Sato I was thinking of Lucy Liu, but was also thinking that she is too young.

Possible actors for the roles

I think the following can do a good job for the following roles, the point is you suggest those actors for a role who have NOT already done similar role(s), for a true actor it is not a challenge!
and there is no surprise for the audience.
Robert Langdon, Harvard symbologist, Protagonist- Tom Hanks (it has to be Tom)
Peter Solomon, Smithsonian secretary, billionaire, Freemason, Langdon's closest friend - Christopher Plummer (the man's got grace and heritage written all over his face, great performer too!)
Zachary Solomon/Andros/Mal'akh/Dr. Christopher Abaddon, Peter Solomon's son, tattoo-covered villain - Vin Diesel (Truly underutilized talent, time for Vin to show he is more than just Muscles! but the role needs some one huge like him... and he can create fear and awe)
Warren Bellamy, Architect of the Capitol, and Freemason - Laurance Fishbourne (need i say more)
Katherine Solomon, Noetic scientist, sister of Peter Solomon- this is a tough one, i would like to see Sharon Stone in this role, she is of perfect age and she is an actress after all (unfortunately stereotyped)
Inoue Sato, Director of CIA's Office of Security- Lucy Liu...hard work to look like Sato (some crazy diet, and good makeup should do it)
Trish Dunne, Peter and Katherine Solomon's assistant - Kirsten Vangsness from Criminal Minds!

Mal'akh choice

Amaury Nolasco as Zach/Mal'akh I think. Could play a drugged out skinny dude and get beefed up and intimidating. Check out his screenshots from Max Payne.

Linda Hunt is perfect for Sato.

The Right Actors & Actresses For The Right Roles

After a painstaking and thorough study and analysis, my choice of actors and actresses for "The Lost Symbol" movie are as follows:

Robert Langdon - Tom Hanks
Warren Bellamy - Morgan Freeman or Danny Clover
Katherine Solomon - Leonor Varela Palmer
Malak'h - Arnold Vosloo
Innoe Sato - Jodi Lyn O' Keefe
Peter Solomon - Anthony Zerbe or Helmut Bakaitis
Dean Galloway - Emm, well, I'm still thinking!

What do you think?

The cast

I pictured Bellamy as Lance Reddick, the guy who plays Agent Broyles on Fringe. He reminds me of a cross between Scatman Crothers and Rod Serling from the Twilight Zone.

Tom Hanks is Robert Langdon for me since I first read the books after I heard he was cast for the part in the Da Vinci Code.

I pictured George Clooney as Peter Solomon

Vin Diesel would be good as Mal'akh if he could pull it off. I pictured Billy Zane on steroids when I read it.

My mind kept picturing Angelica Huston as Katherine, even though I don't find her that attractive and the book described her as so. Also, if Clooney is Peter then this wouldn't work.

Anthony Hopkins as Dean Galloway.

Sato seemed kind of cartoonish to me so I wouldn't be all that disapointed if they changed her character completely

And finally, Cheech Marin as Alfonso Nunez., the unlucky security guard who let it all happen.

Possible actors for Mal'akh

I agree that Vin Diesel would be good if he could pull it off. But when reading about someone with muscles and tattoos, I pictured Dwayne Johnson, The Rock.

Anonymous wrote 7 years 37 weeks ago

Yeah, when I started reading

Yeah, when I started reading Warren Bellamy's character, Morgan Freeman immediately came to mind and that's how I envisioned him. However with Mal'akh, I never associated him with any particular actor, but after reading these comments, I realize that the mental image I created for him does resemble Vin Diesel or Arnold Vosloo quite a bit!

i just finished the book, and have a couple of things to add to what everyone has said about which actors would fit...

Tom Hanks HAS to play Langdon (for MANY reasons)

Linda Hunt HAS to play Sato... google her name and tell me thats not EXACTLY what you had in mind for Sato

Morgan Freeman is a good choice for Bellamy

as for Peter Solomon and Zach/Mal'akh... the actors (and i actually assume Zach and Mal'akh will be two different actors... because the transformation is supposed to be so massive that you would not realize one is the other) need to believable as Father and Son... you cant have someone like "The Rock" or Vin Diesel play Mal'akh and have Patrick Stewart be Peter.... you need a MASSIVE man (6'4", 230-250lb) to play Mal'akh, and he also needs to be able to be CHARMING as Dr Abaddon... this, i assume, will be the toughest person to cast! this is not a "big guy"... this is a man who has the strength to pick a woman up with one hand... hes been using steroids and HGH... this needs to be a MASSIVE man... not that he would have the acting chops to pull it off, but PHYSICALLY i see someone like Bill Goldberg (look him up, and imagin him tattoed from head to toe)

'Tom Hanks comical

Natalie Portman is the incarnation of smart and beautiful (Havard graduate) so for Katherine that would be appropriate

Edward Norton is no where big enough to play malakh I don't understand that suggestion either

Monica Bellucci as Katherine

Although she is a little young, she is immediately who I thought of for Katherine.

Some of you are saying that the rock or desiel should play malake but way. not big enough and not a good look. The guy that played the mummy Arnold vosloo would be the perfect canidate. He is big muscular and would be bad ass covered in tattoos. He is an educted man and would pleay a good doctor too.

Tom Hanks just has to be Langdon - it wouldn't be the same without him.

For some reason, when reading The Lost Symbol, I have pictured Katherine as being played out by Melina Kanakaredes ("Stella" from CSI: New York) - I reckon she would play the part perfectly!

Peter Solomon would just have to be played by Harrison Ford - think this would be a good role for him.

As other people have also mentioned on this forum, I have also pictured Morgan Freeman as "Bellamy"

For one of the smaller parts - Tommy Lee Jones would need to play the role of "Simkins", I think he would be well suited to playing that character.

I am not too sure who would play the role of the main antagonist Mal'akh - can't think of anyone who looks evil enough to play the part - I'll need to give that one some more thought!

Here's my dream team.

Robert Langdon - Tom Hanks (for continuity)
Warren Bellamy - Harry Lennix
Katherine Solomon - Diane Lane
Malak'h - Arnold Vosloo or Ralph Fines
Innoe Sato - Tsai Chin
Peter Solomon – Ian McKellen
Dean Galloway – Antony Hopkins
Simkins – tommy lee jones

Most are who I pictured when reading the book. I also think that there would need to be three characters for the Malakh character as he develops from boy to man / monster. Maybe a great opportunity for an unknown to get a foothold? Seriously though I truly dont want to see any WWE (or whatever its called these days..) in the pivotal role of the villain. Malakah is an articulate and cultured character and one certainly not to be ruined by wrestler meat heads. My thinking is that the true awe and horror of this position would be more about the acting that the muscles.

I was having a really hard

I was having a really hard time deciding who would be good for Mal'akh because he is seriously evil personified! However, I don't see Edward Norton as a bad choice but at the same time I think a new face would be good. But, regardless, he has to be an amazing actor. I think that is more important than him looking like he is on steroids. I agree about Tom Hanks as the original pick too. I feel like we lose sight of Langdon's vulnerability in the movies and I don't know if it is just Hanks or the directing, but I was especially disappointed with Angels & Demons. DaVinci Code, however, was pretty good. Anyways, I didn't actually picture Morgan Freeman as Bellamy, I pictured more of a guy like Laurence Fishburne. I think we can all agree that Linda Hunt is the picture we had in our mind for Sato, just a little scarier. Angelina Jolie would be a horrible Katherine, I think this should also be a new or unknown brunette actress in her 40s/50s like described in the book and less edgie looking...I mean we want her to look more like a scientist, less like a stripper.

Katherine Soloman & Mal'akh

The whole time reading, I was picturing Jennifer Connolly, as she was described having dark hair. She may look young, but she is of age to play Katherine. As Mal'akh I picture Xerxes from the movie 300, although that actor was digitally enhanced but maybe they could do the same for Mal'akh.

I haven't seen the other two films, but I love the books. And for the more youthful Zach (pre-Malak'h and pre-tattoos), it would be great to see Thomas Sangster play him. Look him up! He's best known from Love Actually and Nanny McPhee and Phineas and Ferb, but he's been doing some really deep stuff lately. Like REALLY different roles, more adult.

Wouldn't John Malkovich make a good Peter Solomon? Although he often plays cruel roles, he's great at playing warm people, and he's got the real air of a powerful, wise and smart person.

In My Opinion...

Robert Langdon - Tom Hanks ( NO DOUBT ABOUT IT)
Katherine Solomon - Michelle Pfeiffer (she's about Katherine's age, and same description, the only thing they should change is to put grey eye lenses)
Peter Solomon - I think Richard Gere could be a nice choice, but my feeling is that he should look more wise, too bad Sean Connery is retired. Maybe Harrison Ford or Dennis Quaid?
Mal'Akh - I thout about Vin Diesel for the Mal'Akh phase, but we need to think about the Zachary phase as well, I think maybe Timothy Olyphant could do a nice job.
Warren Bellamy - I thought about Denzel with grey hair or maybe even Morgan Freeman.
Inoue Sato - Maybe Sandra Oh, or even Elizabeth Sung, she's older, but both would have to lose a few pounds to fit the part of Sato
Trish - First one that comes to mind is Ginnifer Goodwin, cause Trish is chubby and Ginnifer has chubby cheeks, but she's very charismatic.

Hope you like my casting !

Keanu should be Mal'akh

I pictured Keanu Reeves as Mal'akh. He can be as elegant and charming as Dr.Abaddon but at the same time can be so evil when covered with tatoos(and some makeup). Keanu is also musled, absolutely the right choice for the role.

that was an exaggeration on my part, and that organizations do not usually try to grab a new technical areas as a lifeguard. Organizations to make a play like that usually are not very good options for a project, though, as you probably already seen as beyond their "sell by" dates. Sometimes things can change, sometimes not. mensagens..

I like the idea of Sigourney weaver as Katherine, although I kept picturing Julia Roberts as I was reading the book.
Tom Hanks for Langdon
For the Architect, I kept hearing Bill Cobbs' voice as I read the book. I don't know about his acting chops, though.
Mal'akh could be pulled off brilliantly by Edward Norton acting-wise. But for looks, I imagined Vin Diesel. I'll take acting over looks any day for this role.
For Peter I kept imagining David Ogden Stiers. That's the picture that came in my head, but again don't know if he has the acting chops for the role. I like the idea of Victor Garber that someone posted earlier.
For Isabel what about Blythe Danner?
Sato was a little hard because I know someone personally that looks EXACTLY like Dan Brown's description. But she cannot act. So I'd go with Linda Hunt.
For Trish Dunne I like Olivia Wilde, and for Zoubianis I thought of Sam Rockwell (geeked out) or Justin Long
What do you all think? Am I missing anyone?

Hugh Jackman is perfect for Mal'akh!

The whole time while reading the book, I kept picturing someone like Hugh Jackman in the role of Mal'akh. He has the perfect stature for the part and he can be both charming and menacing. For the scenes where he needs to be younger, they can always use a bit of CGI (a la Benjamin Button) to make him younger. He's a perfect fit.

But the one thing I do know and by now it's too late(movie premere next summer!!!!!) but I would have liked to see the woman who played "mother" in Memoirs of a Geisha play Sato honestly that wit and naturally raspy voice would be perfect and as much as I LOVE Hunt shes not asian :( just my opinion...

Tom Hanks as Robert Langdon is a given. I always pictured Mal' akh as Alexander Skarsgard. I hear his chilling voice everything I read Mal' akh speak and he's a really big dude about 6'4 or 6'5??. I always pictured Sophie Marceau as Katherine. Linda hunt is an obvious choice for Sato. Morgan Freeman as Bellamy. I read about the first twenty comments are so and I believe I didn't see the name MICHAEL CAINE as PETER SOLOMON. I always pictured Michael Caine as Peter, don't know why. Well this is just my humble take on who should be playing who.
